I'm allowed to sell domains here, right?

Just making sure.

Because on some other admin forum ("AdX"), I created a thread selling four domain names, and it was removed by some abusive global moderator. I registered them almost two weeks ago and was apparently selling them 'too fast'.

 

Im sure you can I dont think it matters whether you bought them last night or not really

 

Seen many sold here no issue.

 

Yes you can sell them here
that rule is just silly imo, removed for "selling them to fast"... wow

 

That is pretty... odd... to say the least. But yes, you are free to sell any and all domains here, no matter how old or new they may be.
